SACRAMENTO — As the state moves to expand healthcare coverage to millions of Californians under President Obama's healthcare law, it faces a major obstacle: There aren't enough doctors to treat a crush of newly insured patients.

Some lawmakers want to fill the gap by redefining who can provide healthcare.

They are working on proposals that would allow physician assistants to treat more patients and nurse practitioners to set up independent practices. Pharmacists and optometrists could act as primary care providers, diagnosing and managing some chronic illnesses, such as diabetes and high-blood pressure.

"We're going to be mandating that every single person in this state have insurance," said state Sen. Ed Hernandez (D-West Covina), chairman of the Senate Health Committee and leader of the effort to expand professional boundaries. "What good is it if they are going to have a health insurance card but no access to doctors?"

Hernandez's proposed changes, which would dramatically shake up the medical establishment in California, have set off a turf war with physicians that could contribute to the success or failure of the federal Affordable Care Act in California.

Doctors say giving non-physicians more authority and autonomy could jeopardize patient safety. It could also drive up costs, because those workers, who have less medical education and training, tend to order more tests and prescribe more antibiotics, they said.

Such "scope-of-practice" fights are flaring across the country as states brace for an influx of patients into already strained healthcare systems. About 350 laws altering what health professionals may do have been enacted nationwide in the last two years, according to the National Conference of State Legislatures. Since Jan. 1, more than 50 additional proposals have been launched in 24 states.

As the nation's earliest and most aggressive adopter of the healthcare overhaul, California faces more pressure than many states. Diana Dooley, secretary of the state Health and Human Services Agency, said in an interview that expanding some professionals' roles was among the options policymakers should explore to help meet the expected demand.

At a meeting of healthcare advocates in December, she had offered a more blunt assessment.

"We're going to have to provide care at lower levels," she told the group. "I think a lot of people are trained to do work that our licenses don't allow them to."

Currently, just 16 of California's 58 counties have the federal government's recommended supply of primary care physicians, with the Inland Empire and the San Joaquin Valley facing the worst shortages. In addition, nearly 30% of the state's doctors are nearing retirement age, the highest percentage in the nation, according to the Assn. of American Medical Colleges.

Physician assistants, nurse practitioners, pharmacists and optometrists agree that they have more training than they are allowed to use.

"We don't have enough providers," said Beth Haney, president of the California Assn. for Nurse Practitioners, "...so we should increase access to the ones that we have."

Hernandez, who said he would introduce his legislation and hold a hearing on the issue next month, said his own experience as an optometrist shows the need to empower more practitioners. He said he often sees Medicaid patients who come to his La Puente practice because they have failed their vision test at the DMV. Many complain of constant thirst and frequent urination.

"I know it's diabetes," he said. But he is not allowed to diagnose or treat it and must refer those patients elsewhere. Many of them may face a months-long wait to see a doctor.

The California Medical Assn. says healthcare professionals should not exceed their training. Phinney, a pediatrician, said physician assistants and other mid-level professionals are best deployed in doctor-led teams. They can perform routine exams and prescribe medications in consultation with physicians on the premises or by teleconference.

Allowing certain health workers to set up independent practices would create voids in the clinics, hospitals and offices where they now work, he said. "It's more like moving the deck chairs around rather than solving the problem," Phinney said.

His group proposes a different solution: It wants more funding to expand participation in a loan repayment program for recent medical school graduates. Doctors can now receive up to $105,000 in return for practicing in underserved communities for three years.

Still, it typically takes a decade to train a physician. Health experts say the pool of graduates cannot keep pace.
